Component	Temp. effect	Humidity effect
Capacitors, Ceramic	Changes in dielectric constant and capacitance, lowered insulation resistance with high temp.
Capacitors, Electrolytic	Increased electrolyte leakage; shortened life, large change in capacitance, increased series resistance with low temp.	Decreased insulation resistance increased dielectric breakdown increase in shorts
Capacitors, Tantalum	Electrolyte leakage; change in capacitance insulation resistance; series resistance	Decreased insulation resistance increased dielectric breakdown increase in shorts
Transistors	Increased leakage current; changes in gain; increases in opens and shorts	Increased leakage current; decreased current gain , if sealed not effect
Connectors, standard	Flash over, dielectric damage	shorts fungus; corrosion of contacts lowered insulation resistance
Crystals	Drift;	Drift;
Switches	Oxidation of contacts	Contacts arcing
Thermistors	Increased shorts and opens	Change in resistance
